Over-Accessorized Cosplay is a cosplay fashion trend that gained popularity on TikTok during the COVID-19 pandemic . The style is characterized by the practice of adorning a pre-existing character's costume with a maximalist profusion of accessories, deviating significantly from the character's original "canon" design. Drawing heavy inspiration from Japanese Decora fashion, the aesthetic prioritizes creative self-expression and individuality over strict accuracy.

The trend is most famously associated with the Danganronpa video game fandom, to the extent that it is sometimes colloquially referred to as "Danganronpacore." It represents a shift in online cosplay culture, where personalizing a character's look with layers of accessories became a distinct and recognizable style in itself.

The trend of over-accessorizing cosplays emerged and was popularized on " Alt TikTok " during the 2020 COVID-19 pandemic lockdowns. During this period, a large and active cosplay community flourished on the platform, with a particularly strong presence from the Danganronpa fandom. Confined to their homes, many young cosplayers began experimenting with their costumes, using easily accessible and often handmade accessories to create more visually dense looks.

This style was a departure from the more traditional emphasis on "canon accuracy" in the cosplay community. Instead of perfectly replicating a character's design, participants would use the original costume as a base and then layer it with elements from their own personal style and other aesthetics, such as E-Girl and Scenecore .

The Over-Accessorized Cosplay aesthetic is centered on the layering of numerous, often colorful and mismatched, accessories onto a character's base costume. The goal is to create a visually crowded and highly personalized look. Commonly used accessories include dozens of handmade kandi bracelets stacked on the arms, multiple chains and chokers (often with spikes or O-rings), rainbow butterfly clips in the wig, and striped or fishnet fingerless gloves. Other popular items are novelty hats (such as bunny hats with moving ears), belts with grommets, and an abundance of safety pins. The specific accessories often reflect the individual's personal taste, blending the character's identity with the cosplayer's own.

The Over-Accessorized Cosplay trend has been the subject of two main points of criticism within the online community. The first is a general debate regarding its deviation from "canon." Some members of the broader cosplay community argue that the excessive accessorizing detracts from the character's original design, making it unrecognizable and visually overwhelming. Proponents of the style, however, defend it as a valid form of creative expression and individual interpretation.

A more serious and widespread controversy arose from the alleged practice of some participants incorporating used sanitary products, such as tampons and menstrual pads, into their cosplays as accessories. This trend, which reportedly occurred around 2020-2021 and was also associated with the Danganronpa fandom, was widely condemned for being unsanitary, socially inappropriate, and created for shock value. While verifiable video evidence is scarce due to platform takedowns, numerous anecdotal accounts on Reddit and other social media platforms attest to its existence.
